When an NPC ventures into a deathtrap, naturally they should end up dead. Since the function of most DT's ( old school feature ) is to destroy the equipment and corpse of the victim, an NPC has no reason to be transferred out. They should be removed from play immediately. Under worst case scenarios, the death room for players could fill up with mobs if a DT is in a heavily trafficed area. Although amusing for admins to see, it's not much fun for players
